Usage

In order to use the Metathesaurus, you'll need to get an API key for access from the National Library of Medicine, which you can sign up for here.

You can then install this module by running pip install cumulus-library-umls.

This will add a umls target to cumulus-library. You'll need to pass your API key via the --umls-key CLI flag, or set the UMLS_API_KEY environment variable to the key you received from NIH.

This ends up being a fairly intensive operation - we download a large file, extract it, create parquet files from Athena, and then upload it. It usually takes a half hour to run. We try to preserve some of those artifacts along the way to make rebuilds faster. If you need to force recreation from scratch, the --force-upload CLI flag will handle this.

Licensing details

The cumulus-library-umls study is provided as a convenience to install the UMLS Metathesaurus, but is not shipped with the Metathesaurus dataset. It will require an API key to download the data from NIH directly.

As a reminder, the License Agreement for Use of the UMLS® Metathesaurus® provides several restrictions on this usage of this data (including distributing the dataset). When you sign up for a UMLS key, you are assuming responsibility for complying with these terms, or an alternate licensing agreement with the owner of the Metathesaus data if you are provided with one.
